When a new memory forms the brain undergoes physical and functional changes known collectively as a “memory trace.” This memory trace represents the specific patterns of neuronal activity and ...

Scientists at UW Medicine, University of Washington, and their collaborators have pinpointed exactly when cytotoxic T lymphocytes form memories during infection. They also examined the epigenetic ...

Neuroinflammation, a prolonged activation of the brain's immune system prompted by infections or other factors, has been linked to the disruption of normal mental functions. Past studies, for instance ...

Neurons have variable levels of chromatin compaction, shown as different shades of red. The less compact a neuron, the more likely it is to be recruited into the memory trace (green). When we form a ...

Our experiences leave traces in the brain, stored in small groups of cells called “engrams”. Engrams are thought to hold the information of a memory and are reactivated when we remember, which makes ...

An epigenetic "memory" of obesity has been found in helper T cells, which could cause dysregulation of some immune system ...

Scientists say they have found a pattern of so-called epigenetic 'marks' in a transition state between normal and pancreatic cancer cells in mice, and that the normal cells may keep at least a ...

Obesity rates are increasing in the United States and around the world, and the condition has been linked to increases in the risks of a wide range of health disorders, including diabetes and ...

Coral can remember the past. Not in the same ways people do, of course, but they do form a sort of memory at the molecular level — a record of the stressful times punctuated by periods of pollution ...
